[kpachbiu88]

You can use this code for add support Webpack v5

import { Compiler } from 'webpack';

interface SaveRemoteFilePluginOptions {
	url: string
	filepath: string
}

class SaveRemoteFilePlugin {
	pluginName = 'SaveRemoteFilePlugin'
	options: SaveRemoteFilePluginOptions[];

	constructor(options: SaveRemoteFilePluginOptions[]) {
		if (options instanceof Array) {
			this.options = options;
		} else {
			this.options = [options];
		}
	}

	apply(compiler: Compiler) {
		const { webpack } = compiler;
		const { WebpackError } = webpack;
		const { RawSource } = webpack.sources;

		compiler.hooks.compilation.tap(this.pluginName, async (compilation) => {
			compilation.hooks.additionalAssets.tapPromise(this.pluginName, async () => {
				const downloadFiles = async (option: SaveRemoteFilePluginOptions) => {

					try {
						const { url, filepath } = option;
						console.log(`Downloading file ${url}...`);
						const resp = await fetch(url);
						const arrBuffer = await resp.arrayBuffer();
						
						compilation.emitAsset(
							filepath,
							new RawSource(Buffer.from(arrBuffer))
						);
						console.log(`Downloading finished`);
					} catch (err) {
						console.log(err)
						if (err instanceof Error)
							compilation.errors.push(new WebpackError(err.message));
					}
				};

				for (const item of this.options) {
					await downloadFiles(item)
				}
			});
		});
	}
};

export default SaveRemoteFilePlugin;

Would you be willing to do this via a PR?

Unfortunately, I don't have free time for open-source contributing.

There was a task at work, but this library is only compatible with the old version of Webpack 4 and I made a plugin for Webpack 5, but in the end, the problem was solved differently.

I shared the code because it might be useful for someone.
